To all whom it may concern Be it known that. I, CHARLES S. FORBES, a citizen of the United States, residing at Brookline, county of Norfolk, State of Massachusetts, have invented an Improvement in Spinning-Rings, of which the following description, in connection'with the accompanying drawing, is a specification, like characters on the drawmg representing like parts.

This invention relates to spinning rings of that type embodying an annular traveler which is confined between annular top and bottom members, examples ofspinning rings of this type being shown in United States Letters Patent No.'857,535, dated June 18, 1907; No. 874,429,dated December 24, 1907, and No. 957,759, dated May 10, 1910.

The object of the present invention is to provide an improved spinning ring-of this type which is constructed to reduce to a minimum the Wear of the traveler upon the lubricating lining and the wear of the traveler on the yarn, and which is also constructed to provide a spinning ring capable of an increased speed -of operation, and

otherwise to improve spinning rings of this type, all as will be more fully hereinafter set forth.

In the drawings wherein I have illustrated a selected embodimentof my invention, Flgure 1 shows a plan View of a spinning ring constructed in accordance with the invention;

hemain elements of my improved sp nning ring are the same as are found 11 prior spinning rings of this type, that 1s, the

spm-nmg ring comprises an inner member lhaving an upturned flange 2, an outer member 3 which sets over the inner member 1 and embraces the flange 2, a bearing member 4: which fits within the outer member '3 and encircles the flange 2 of the inner member 1 and which has an inwardly-projecting flange 5 that overlies the upper edge of the flange. 2 but is separated therefrom, and an annular traveler 6 which is received in the space between the flange 2 and the bearing member 4 and is provided with an up- Wardly-directed stem 7 having a, yarn guide 8 at its upper end.

The inner and outer members 1 and 3 are (letachably secured together so that they can be readily separated in usual mamier. that is, the outer member 3 is provided with the extension 9 having a notch to fit the retaining lip 10 on the inner member 1, and said parts in position' The rail plate 13 is provided with two pairs of oppositely-disposed notched projections 16, 17, these projections being for the purpose of receiving screws for attaching the rail plate to the ring rail. The purpose of providmg two pairs of proprovided with the up:

JectiOns is so as to permit the rail plate to 4 v be attached to the ring rail in either one of? two positions, depending upon which pait" of notched projections is used.

One of the features of my present invention relates to a construction of the bearing member 4 by which the wear thereof due to the rotation of the traveler is greatly reduced. In spinning rings of this type, this bearing member 4 is usually made of wood which has been treated with some lubricating material for the purpose of making it self-lubricating. In the use of the spinning ring,the traveler rotates very rapidly, and in order to eliminate as far-as possible any wear on this bearing member due to the action of the traveler, I propose to provide the surface thereof with which the traveler contacts with one or more wear-resisting inserts. These wear-resisting inserts will take the wear of the traveler and will prevent the Wood from wearing away to any appreciable extent. These inserts may be provided for in various ways without departing from my .invention. I have herein shown the inserts in the form of metallic pins 18 and 19. The pins 18 are arranged horizontally and are situated in the plane of the traveler 6 so that said pins will take the wear of the traveler. The pins l9-are arranged vertically and are so positioned that they come flush with the inner face .21 of the bearing member 4. These wear-resisting inserts will receive the wear of the traveler but will not interfere with the-action of the bearing member in providing necessary lubrication. \Vhile I have shown both vertical and horizontal pins, yet it may not be necessary in all cases to use both sets of pins and the wear-resisting inserts. may be either horizontally or vertically arranged without departing from the invention.

The traveler 6 is made of sheet metal and it is provided with one or more depending and yarn guide.

same weight as the stem 7 and yarn guide 8,

and by this means, a perfectly balanced ,tr. veler is produced. If desired more than one apron may be used, and these other aprons may be placed at variouspositions about the traveler, but if added-aprons are used, they will preferably be so placed that they will balance each other! The yarn guide 8 is formed by bending the end of the stem into proper shape, and

in doing this, the extremity 22 is carried up arallel to the stem above the center of the 00p thus formed and which constitutes the yarn guide 8. The space 23 between the extremity 22 and the stem 7 forms a thread passage through which the yarn n be threaded, and by having the thread passage 23 lead into the guide eye 8 above the center thereof, there will be no danger that said yarn guide will be tie-threaded when the yarn 'becomes slack upon stopping the spinning machine.

It is desirable that the traveler should be as light as possible consistent with its having the requisite strength, and to this end I propose to make the traveler of very thin material and to make the stem as narrow as -possible. In order to strengthen the guide eye 8, I propose to make the portion of the stem from which said guide eye is formed with a transverse curvature and in order to produce a arn guide which will present a smooth sur ace for the yarn, I will make this curvature such that the inner face 44 of the eye 8 is convex in a direction transversely to the stem. This manner of forming the yarn guide 8 not only makes a smooth thread-engaging surface, but also adds to the strength.

The extremity 22 of the stem is made rounding, as shown in Fig. 8, so as to facilitate the de-threading of the eye if occasion for this should arise. The stem 7 is connected to the traveler by an offset portion 45 so that-the stem is situated inside of the inner periphery of the traveler. The. advantage of this construction is that it permits the traveler to set farther under the overhanging flange 5 of the 'wooden bearing member or, in other words, it permits this flange 5 of the wooden bearing member to be made wider than would be possible if the stem 7 extended directly up from the inner periphery ofthe ring. With this construction, the traveler will be more securely held in place and all-danger that it will be pulled out from under the flange 5 is obviatedQ I will also preferably make the traveler curved transversely, as seen in Fig. 7, thereby, to give it additlonal strength. The outer edge of the traveler will also preferably be bent inwardly, as shown at 24:, to form a stifiening bead which adds to the strength of the traveler. This bead also has theadvantage that it produces a rounded edge which tends to lessen the wear of the trav-' eler on the bearing member 4. By makin a traveler with the stiffening bead 24 an of the shape shown, it is possible to use very thin material for the traveler and yet have it suiiiciently stiff and rigid to meet all requirements. 2

, It is important that the bearing member 4 should 'fit tightly up against the top flange of the outcr member-3 so that the portion '5 of said bearing member may be properly spaced from the outer edge of the flange 2 and of the inner member 1. In the manufacture of the bearing member 4, it-is found that the vertical dimensions of said member. vary somewhat, due to the'fact that some woods will shrink more than others. In order to provide for maintaining the bearing member 4 in proper position regardless of any slight variation .in its vertical dimension and also to provide for holding said bearing member firmly in place and to prevent its rotating, I propose to provide the inner member 1 with a plurality of retaining projections 27 which aresituated to I engage the under face of the bearing member 4. These retaining projections 27 are made with sharp points so that when the outer member is snapped onto the inner member, these projections will be pressed into the under face of the wooden bearing .member 4 and will thus hold said bearing member in position. The pressure of these points 27 against the bearing member will also force said bearing member firmly against the flange 25 of the outer member and thus hold said bearing member securely in position. This result will be attained even though the bearing member varies in vertical dimension somewhat because if the bearing member is slightly thicker than is shown in the drawing, the points 27 will merely be pressed farther into the bearing member, while if said bearing member is of less thickness than shown in the drawings, the said points will be pressed thereinto to a' less degree.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a spinning ring, the combination with an inner member and an outer member, of a self-lubricating bearing member confined between said inner and outer members and an annular traveler situated between .resisting inserts extending through the a 'by the traveler as it rotates.
